Worked Analysis of Oasys

The process of diagnosing occupational asthma from serial peak flow records using Oasys contains the follwing steps:

1. Ask the patient to measure their peak flow every two hours from waking up until going to bed.
   
2. Download the latest version of Oasys from this website if you have not already done so.
3. Register with this website if you have not already done so.
4. Enter the data into Oasys.
5. Look at the Oasys report for the record.
6. Interpret the results.

Please click on the links to find out more about the individual steps, or to actually complete the steps (for registering and downloading the latest version of Oasys).

You can also look at the more traditional serial plot, although we don't think this is as useful as the other graphs and we don't recommend it.
